Yes! Sorry I did not tell you SafeGuard is a dewormer for canines. Ideally Flubenol 15 is manufactured for aquarium use for its water solubility, but I think you can only find that in UK.
I agree, I would have used bloodworm too. Pellets will also be able to soak up the tx solution as well. Don't forget Camallanus has 30 days life cycle, as Sena suggested, disinfect everything thoroughly. I have read bleach is ok, but must be diluted and let sit. The key word is rinse....lots of rinsing, letting it sun dry and rinsing again. Just do what you think is easiest for you.
This info will be helpful for dosage:
"This wormer is Fenbendazole.
So, he contacted an aquatic biologist friend, and they worked out a dosage.
Dissolve 3CC of powdered Fenbendazole in 100ml of water.
Mix well, then add as many bloodworms as you need to feed your fish. Soak for 30 mins to 1 hour, then dump the entire container in the tank, water and all.
So, for 14.35 in cost, I picked up my Fenbendazole in powder/crushed form.
The brand name it goes under is Panacur.
I brought it home, and prepared the first dose.
It seemed to really soak into the bloodworms, changing them to a slightly lighter and grayish color tone.
I fed the fish 2x A Day for 2 days.
I watched the affected fish carefully.
Within 36 hours, all worms have withered and dropped away from the affected fish.
Within 48 hours, I could find no remaining fish with Camallanus Worms protuding.
I followed up with a good gravel vac and a large water change.
I repeat this treatment in 2 weeks time, and then again in 2 weeks following if need be.
I have enough medication to do at least 7 more doses.
However, I dont think I will need it."
